Description

Technical Field

[0001] The utility model relates to the technical field of sanitary napkin production, in particular to a cotton wool removing device for sanitary napkin production. Background Art

[0002] Sanitary napkins are a type of sanitary product used by women during menstruation. The main materials are cotton, non-woven fabrics, pulp or polymers and polymer composite paper formed by composites of the above materials. During the production process of sanitary napkins, cotton wool and other sticky flocs on the roll must be removed.

[0003] The removal device removes excess cotton wool and flocs before the sanitary napkins are pressed together. However, the removal device mostly uses suction to remove the flocs. During the suction process, there are problems of incomplete removal and raw materials being sucked in. For example, the flocs that adhere tightly during the suction process do not fall off completely, and there is a lack of limiting structure. During the suction removal process, the sanitary napkin raw materials are directly sucked in, affecting the processing efficiency.
